Letters Patent No. 90,544, dated May 25, 1869.

IMIPROVEIENT IN S.

The Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may concern Be it known that I, JAMES S. HUFFMAN, of Brownsburg, in the county of Rockbridge, and State of Virginia, have invented a new and useful Improvement in Chorus; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view.

Figure 2 is a horizontal section.

Figure 3 is a detached view of a segment of the flywheel;

This invention is a novel and convenient attachment for operating the common upright churn, so constructed as to be adjustable to the height of the operator, and to have the 'means for adjusting the stroke of the dasher, so that the latter. can be operated with more or less power and velocity, and with different lengths of stroke. It can be used with any upright churn,new

or old, without any change therein.

D is an adjustable staff, extending vertically throughthe top of the tripod, and capable of being fixed at different altitudes by means of the set-screw d.

E is a horizontal table or board, afiixed to the staff 1), above the tripod, and having its outer end adapted to fit to the side of the churn, as seen in figs. 1

and 2.

One side, E, of this table is a detachable piece, ca pable of being forced firmly against the edge of the outer piece, by means of a screw, 6, so that the two parts of the table operate together as jaws, to receive and securely hold the churn during the operation.

The staff D is provided with two short horizontal arms 35 F on the side next to the churn, having slots which guide and support a vertically-reciprocating rod, G. The latter is provided with an arm, H, the end of which receives and holds the handle of. the churndasher, which can be. adjusted higher or lower by a set-screw, pins, and holes, or any other suitable device.

I I are two short horizontal arms affixed to the side of the staff 1), opposite to the arms F F, and supporting an upright piece, I.

'J is a crank attached'to a shaft, K.

Lisa large gear-wheel on shaft K, gearing into and operating a small one, M, on a short shaft, m,

above the two gear-wheels, operating in the vertical slot between the parts D I.

N is a large fly-wheel, supported on the end of shaft m, and running in the space between the parts D G.

This fly-wheel is connected to the vibrating-rod G by means of a pitman, P, so that themotion of the crank J operates the churn-dasher.

The pitman P is attached to one arm or spoke of the fly-wheel by an adjusting-device, shown in fig. 3, and consisting of a radial slot, 0, in the arm, and a movable wrist-pin, capable of being fixed in different positions, up and down the slot, by means of a screwnut, 'r, on one end, and head on the other.

The device thus constructedis specially designed for convenience of operation, it being so madeas to be adjustable as follows:

First, by raising or lowering the stali D, it accommodates itself to persons of different heights.

Secondly, by adjusting the dasher up and down in the socket H, it can be made to operate at the bottom of the churn, or near the surface oi the milk therein, as may be desired.

Thirdly, by adjusting the wrist-pin 'r in the slot 0, the churn may be made to operate more or less easily, according to the strengthof the operator.

Fourthly, by the means last mentioned, the length of stroke can also be adjusted to the quantity of milk in the churn, so that, while the dasher operates throughout the whole depth of the milk, it will not rise above the surface thereof at any part of the stroke, and thus waste a portion of the power applied.

The clamping-table E E is a very convenient device, easilyand quickly operated, not liable to get out of order, cheap in construction, and very serviceable in holdingthe churn steadily, so'that the dasher-staff shall vibrate in a line with its vertical axis, wherebythe hole in the cover may be made to fit the stafifmore tightly, so that the milk shall not spatter therefrom.

Having thus described my invention,

What I claim as new, and desire to secure by Let,- ters Patent, is-- I 1. In a churning-apparatus, having the upright shaft D and crank J with which to operate the dasher B, making the staff vertically adjustable in a stand, 0, by means of the set-screw d, or its equivalent, substantially as and for the purpose specified.

2. The combination of the parts E E a, when constructed witha recess to fit around the side of the churn, and adapted to receive and holdthe latter, in manner and for the purpose substantially as described.

To the above specification of my improvement, I have set my hand, this 5th day of February, 1869.
